# Add Nix flake for reproducible development environment This pull request introduces a Nix flake (`flake.nix` and `flake.lock`) to provide a reproducible development shell for NuttX using Nix and flakes. ## Summary - Adds a `devShell` with all required build tools and dependencies for NuttX, including CMake, Ninja, GNU Make, clang-tools, ARM toolchain, and other utilities (automake, bison, flex, genromfs, gettext, gperf, kconfig-frontends, libelf, expat, gmp, isl, libmpc, mpfr, ncurses, zlib, kconfiglib). - Uses `flake-utils` to support multiple platforms. - Sets up a shell hook to enable CMake compile commands and provide a welcome message. - Based on `nixpkgs` `nixos-unstable` for up-to-date packages. **Purpose:** This change simplifies onboarding and ensures a consistent build environment across contributors. By pinning dependencies, it reduces "works on my machine" issues and makes it easier for new developers to get started with NuttX. **References:** - Nix Flakes documentation: https://nixos.wiki/wiki/Flakes - Dependencies gathered from `tools/configure.sh` ## Impact - **Users:** No impact on runtime or target builds; this only affects developer tooling. - **Build Process:** Developers can now use `nix develop` to enter a fully provisioned shell with all necessary dependencies. - **Documentation:** Usage instructions can be added to the repository documentation if desired. - **Compatibility:** The flake is designed to work on all major platforms supported by Nix. ## Testing - Verified by running `nix develop` and building NuttX on `x86_64-linux` with `cmake` and `make` (NixOS unstable, GCC ARM toolchain). - Confirmed that all required tools are available in the shell and that the build completes successfully. - No changes to target firmware or runtime behavior. -- This is an automated message from the Apache Git Service.
